Scientists develop tools to make more complex biological machines from yeast
Date:3/20/2012

iological machines could help to improve things such as pollution monitoring and cleaner fuels, which could make a difference in all our lives."

Dr Benjamin Blount, first author of the paper from the Centre for Synthetic Biology and Innovation and the Department of Bioengineering at Imperial College London, says: "Our new approach to re-wiring yeast opens the door to an exciting array of more complex biological devices, including cells engineered to carry out tasks similar to computers."

In the study, the Imperial researchers modified a protein-based technology called TAL Effectors, which produce TALOR proteins, with similar qualities to wires in electronic devices. These TALORS can be easily re-engineered, which means that they can connect with many DNA-based components without causing a short circuit in the device.

The team says their research now provides biological engineers working in yeast with a valuable new toolbox.

Professor Richard Kitney, Co-Director of the Centre for Synthetic Biology and Innovation at the College, adds: "The work by Dr Ellis and the team at the Centre really takes us closer to developing much more complex biological machines with yeast, which may help to usher in a new age where biological machines could help to improve our health, the way we work, play and live."

Professor Paul Freemont, Co-Director of the Centre for Synthetic Biology and Innovation at the College, concludes: "One of the core aims of the Centre is to provide tools and resources to the wider scientific community by sharing our research. Dr Ellis's team has now begun to assemble characterised biological parts for yeast that will be available to researchers both in academia and industry."
